Eclipse GEF - Locking ConnectionAnchors to positions on a Figure

Is there a method for locking connections in place when connecting to figures. I am using connection anchors and have specified the vertical and horizontal offsets for the anchors in each f开发者_JAVA百科igure. After connection is established, if the figures are moved, then the position of the connection on the figure is changed.

It turns out that I hadn't modified the getTargetConnectionAnchor(ConnectionEditPart connEditPart) method to pass back the correct anchor, as I had with the getTargetConnectionAnchor(Request request) method.
